I want to keep whatever compressor is in the car, I dont want to lose my ice cold freon.



im told this is the non ps bracket, its pretty easy to tell from the PS one, just not sure if they came both ways or not, plus Im not sure if I can even get a good measurement out of mine on the car now without taking it off, its a slight bit off Ill have the welder fill it and I can re-drill I suppose



Im going to run cosmo ribbed pulleys and switching the stock v-belt pulley on my compressor to a FD ribbed pulley as well.

COSMO RIBBED PULLEYS WILL NOT WORK WITH THE AC PULLEY

why not? a ribbed FD pulley ?

Heres why:



The Setup:

13B Front Iron

S4 NA front Cover

S4 NA Water Pump Housing and waterpump

FD ALT

Cosmo 13B-RE MAin Pulley

Modified 13B-RE Water Pump Pulley

S4 NA AC Only Bracket

a pic I have of a cosmo engine shows it actually having a v-belt for the ac, the set of pulleys I got from a cosmo engine actually had NO ac, lol



your pulley looks like a ribbed and a v-belt as well



so I got a FD pulley coming my way anyhow, otherwise I will use the v-belt for the AC with the stock S4 pulley, either way I needed the ac bracket without the powersteering

The AC is a V-belt, the alt/waterpump/main is ribbed.



This setup does not have enough clearance to install the V-Belt between the waterpump pulley and the AC Belt Pulley on tha crank



This is after remove the airpump pulley from the waterpump cosmo pulley

but wait, there is more!



who would have thought you could run a single belt like that?

Installiing the Cosmo Water pump housing is NOT an option with the S4 Front cover either

The front cover(s4) interfers with the waterpump housing(Cosmo)

it can be done with a custom main AC pulley, but so far I have not found a working combo using stock Mazda pulley combos
